  • the step member 122 may thus be said to move between an upward-rotated orientation in the retracted position ( Figure 5) to a downward-rotated orientation in the deployed position ( Figure 3).

  • the retractable step 120 provides a sturdy step for a vehicle user when in the extended position B.
  • the geometry of the stepping member 122, support arms 130, and frame 134 causes the arm 130a to be loaded in tension and the arm 130b to be loaded in compression when a load is applied to the stepping deck 124 in a manner similar to that shown in Figure 1.
  • the arm 130b urges the arm 130a against a stop 152 when a user steps on the stepping deck 124, by applying a horizontal reaction force to the step member 122.
  • the stop 152 prevents motion ofthe drive arm 138 beyond a location chosen so that when the drive arm 138 strikes the stop 152, the step 120 is in a configuration where it tends to move further away from the retracted position upon application of a load to the stepping deck 124, but is prevented from doing so by virtue of the stop. Due to this convergence of factors, the extended step 120 firmly maintains its deployed position without input from motor 146 (discussed in further detail below), when stepped upon by a user.
  • the drive system 137 may advantageously include a system to stop the motion ofthe step member, arms, etc. when an obstruction is encountered within the range of motion of the step, or within the moving parts of the step.

  • the retractable step thus utilizes a relatively compact linkage system to support the stepping deck 124 when in the deployed position.
  • the relatively short, compact support arms 130 can be made of minimal width, as can the frame 134 and support bracket 126.
  • the stepping deck 124 can thus be made substantially wider than the frame/support arms/support bracket.

  • Figure 6B shows the stepping deck 124 of the retractable step after it has moved to the extended position (upon opening the front door 202 or in response to other actions as detailed above).
  • the deck 124 provides a convenient step assist for a person desiring to enter the vehicle through either of the doors 202, 204. Where the deck 124 extends in front of about 1/4 of the width of each door, the deck will be sufficiently wider than the user's foot to provide an easy-to-use step. Extending the deck to cover about 1/2 the width of each door provides an additional safety factor above a 1/4- width deck. A deck which extends across substantially the entire width of both doors is most advantageous in that it essentially eliminates the need for the user to look down to the step when placing a foot upon it, facilitating easy use by a person carrying a large number of items with them.
  • the novel configuration of the retractable step permits the width of the stepping deck to be selected largely independently of the width of the frame, arms and/or support bracket. Consequently, a stepping deck that is intended to serve as a step for two adjacent doors need not extend the entire width ofthe doors. It may instead be only about 4-5 feet wide (in comparison to a standard fixed running board which is typically 6-8 feet in width), providing a convenient step while keeping the size and weight of the overall device to a minimum. It has been found that this particular width provides an optimal balance between providing ease of use (via a relatively wide deck) and avoiding an overly large, bulky device. Likewise, the stepping deck of a refractable step intended for use with a single vehicle door may be reduced to an optimal deck width which is less than the entire width ofthe door.

  • the rearward surface of the front support arm 530a tapers forward at upper and lower transitions 543a, 543b, thus forming a thinner intermediate portion 545 between thicker end portions 549a, 549b.
  • This arrangement permits the arms 530a, 530b to nest partly "within” each other at the extremes of their range of motion, which in turn increases the range of motion of the step member 522 while permitting the ends of the arm(s) to be made thicker, to better withstand the forces encountered at their rotatable connections to the frame and step member. With a greater range of motion thus imparted to the arms 530a, 530b and step member 522, the member 522 can extend farther from the vehicle when deployed and retract further into the vehicle for improved concealment.
